BAG.

SPECIFICATION forming part of Letters PatentNo. 775,268, dated November15, 1904. 7 Application filed January 12, 1904. Serial No, 188,717, '(Nomodel.)

To (LN, whom, it may concern:

Be it known that I, WILLIS P. FLOWERS, a

ton, in the county of Lackawanna and State of Pennsylvania, haveinvented certain new and useful Improvements in Bags, of which i thefollowing is a specification.

This invention provides a bag of novel formation designed mostparticularly to be constructed of cheap stufi','as paper .or like sheetmaterial, stiff yet perfectly flexible, so as to be rolled or folded,but retain the creaselines. I I

The object of the invention is to stiffen the sides of the bag, wherebythe same'will stand to facilitate filling, to devise a constructionwhich will enable the bag to be cheaply'and quickly formed from a stripthe longitudinal edges of which are folded and the strip doubled uponitself and the folded edge portions pasted or similarly secured by acementitious material, and to infold the bottom to provide forcorresponding expansion thereof with the sides to equalize the strain onthe bag when filled with any commodity or material to be stored orcarried therein.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreffecting the resultreference is to be had to the following descriptionand drawings hereto attached;

While the essential and'characteristic features of the invention aresusceptible of modi fication, still the preferred embodiment of theinvention'is illustrated in the accompanying drawings, in Which Figure 1is a view of the blank from which the bag is constructed, the dottedlines indi cating the various folds or creases. Fig. '2 is a perspectiveView of the blank, showing a longitudinal edge portion folded andgummed. Fig. 3 is a perspective view of the blank, having bothlongitudinal edge portions folded and gummed and the blank doubled uponitself to form the bottom, which is infolded, the side portions of thebag beingseparated. Fig. 4

pleted. Fig. 5 is a top view of the bag as it appears when expanded.

Corresponding and like parts are referr' tom the following descriptionand indicate in allthe views of .the drawings by the sam referencecharacters.

Thelblank- 1 is:.of' rectangular formatior and .isi'ofa-sizedependingupon the capacity ofxthe completed bag. Longitudinal edgeportions of. the blank are folded upon the blank andrefolded toform thebellows fold 2 and is again refolded to form the securing-flap 3,

which is gummed or provided with any cementing material forsecurance-ofthe edg portions after the blank has been doubl upon itselfto form the inclosing sides. of t bag. After the longitudinal edgeportioi-l of the, blank have been folded to provid the bellows fold 2and securing-flaps 3' till I blank is doubled upon itself intermediateof its ends, as indicated at 4, and refolded along the lines 5 parallelwith the fold 4 and equidistant therefrom, whereby the fold .4

comes between the sides 6 of the bag and con; stitutes, in effect, aninfold. The blank, with its longitudinal edge portions folded andrefolded, is doubled upon itself to cause the foldededge portions toface outward, and the end portions are refolded along the lines 5 tobring the folded. edge portionstogether, and by moistening or gummingthe securing-flaps 3 they are caused to adhere, thereby securing thebag, as indicated most clearly in Fig. 4:. The securing-flaps 3 unitedlyform stiffeners or side stays 7, which are intermediate of the sides 6anti are connected therewith by the bellowsv fold 2. When the bag isexpanded, as indicated in Fig. 5, the side stays 7 face inward and causethe bag to stand alone, whereby the filling of the same is ren-,

dered comparatively easy and the work greatlv facilitated.

The construction is such as to admit of the material being reeled anddrawn from the roll and cut into lengths of predetermined size, thelongitudinal edge portions being folded simultaneously with the drawingof the strip from the roll. The construction is such as to cheapen themanufacture of'paper bags and to economize in material as well as toprovide an article possessing superior merits.

775,268 BEST VALABLE COP iper bag constructed substantially as describedis slipped within a sack of or other textile, the same formingare toresist the strain and to prevent rup- ,f the paper bag, which, ineffect, constia lining. As the paper bag is filled it rls until thelimit of the textile sack is 1. The inner and outer sacks must be 11relative proportions that when the k is expanded to its fullest capacityJuul' sack or lining retains a fullness,

reby imposing the entire strain upon the Aer sack. The paper comprisingthe inner ,k is preferably chemically treated to ren- ;r it both acidand water proof, as well as to ose the pores and prevent the escape ofany dor from the material. While provision is aad for transverseordiametrical expansion of the inner sack, it is contemplated to allowEfor longitudinal expansion, and for this purpose it is proposed tocorrugate or flute the sack transversely, as indicated at 8 in Fig. 4,:the fluting being effected in any determinate way, as by passing thesack or the blank between eorrugating-rolls.

Having thus described the inventiomivhat is claimed as new 1s 1. A bagformed of a blank having its longitudinal edge portions folded alikethroughout the length of the blank to provide consecuring-flaps anddoubled upon itself transversely and refolded parallel with thetransverse fold, the securing-flaps being united to provide side stays,substantially as set forth.
